MACHINE FOR MAKING PACKING AND LINING FABRICS.

SPECIFICATION forming part of Letters Patent No. 430,447, dated June 17, 1890.

Application filed May 23, 1889. Serial No. 311.793. (No model.)

To all whom it may concern:

Be it known that 1, ROBERT H. THOMPSON, a citizen of the United States, residing in Brooklyn, in the county of Kings and State of New York, have invented certain new and useful Improvements in Machines for Making Packing and Lining Fabrics, of which the following is such a full, clear, concise, and exact description as will enable others skilled inthe art to which my invention appertains to make and use the same, reference being had to the accompanying drawings, forming part of this specification.

The invention relates particularly to improvements in machines for manufacturing packing and lining paper consisting of a sheet or strip of fluted paper affixed to a sheet or strip of plain paper or similar material, so as Heretofore in such machines only two intermeshing rollers have been used to corrugate the fluted sheet, which rollers had to move slowly in order to insure the making of corrugations of sufficient depth and permanency, and the paste or adhesive substance by which the sheets were secured together was usually applied so as to entirely coat one surface of the plain sheet, while only a portion of such surface could be broughtin contact with the corrugated piece, thus wasting the paste and supplying an extra mass to be dried outbefore the paper wasin condition for use.

The object of my invention is to overcome these defects and to construct a machine which will produce the necessary corrugation upon the strip of paper to be fluted without breaking or cutting it, give such corrugation permanent set, while at the same time allowing rapid motion to the corrugating-rollers, and will, moreover, apply the paste or-adhesive material by which the fluted and plain strips of paper are held together in such a manner as to shorten the time necessary for drying and prevent waste; and the invention consists in the devices and combinations of devices, as hereinafter described, and pointed out in the claims.

In the accompanying drawings, Figure 1 is a plan view of a machine embodying my improvements; and Fig. 2 is a vertical longitudinal section of the same, taken on the line X X of Fig. 1. Fig. 3 is an enlarged sectional view of the corrugating-rollers, and Fig. 4 is an enlarged isometric view of the same.

At one end of the frame A is conveniently secured the roll 13, from which the paper to be corrugated is drawn over the guiding and tension rollers 19, b, and b to the primary corrugating roller O. Supported by suitable bearings and in rolling contact with the primary roller C are two or more rollers E, E, and E provided with similar corrugations.

The rollers E, E, and E are preferably of different sizes, as shown in the drawings, the first one ortwo rollers being of comparatively small diameter to draw in the paper and give it the set intended, while the large roller E which, with roller O, may be kept highly heated by steam admitted through the pipes f f in the usual manner, gives the flutes formed by the first roller or rollers the proper heat and pressure to make them permanent. The small rollers E and E are also preferably heated by steam admitted through pipes f f As the corrugating-rollers are all held together under considerable pressure and the small rollers are of small diameter in comparison with their length and inclined to bend, they may be stiffened and supported between their journals by the pressure-rollers c e, mounted on the shafts e2 e pro-- vided with suitable bearings and adjustingscrews e and c. If desired, however, grooves may be formed in the rollers E E and sta tionary pressure-bearings substituted for the rollers e e. Curved bands 0 c are also preferably extended partly around the primary roller O and between this roller and the rollers E E in which grooves are formed to allow for the same,in order to prevent any tendency of the paper to bulge out between the rollers as it passes through, the last roller of the series, under which it is not necessary for the bands to extend, curing any defects in the corrugations from the paper passing beneath the grooved portions of the first rollers.

Conveniently located with reference to the corrugator is the tank or box F, for holding paste or other adhesive substance, with the roller F extending into the paste and provided with a small roller 9, placed adjacent thereto, to press off the superfluous paste and prevent too large a quantity from being deposited on the sheet of fluted paper, which as it passes from the corrugating-rollers is held down over the roller F by the small guiderollers g 9 After the paste has been applied to the fluted sheet, by means of the roller F, it is led over the roller G where it is brought in contact with the plain sheet or backing and together rolled up upon the roller H.

Beneath the roller G is shown an inkingroller I and printing-roller I, together with guiding and tension rollers K K K whereby the plain sheet as it'is drawn from the roll L may have its outer surface marked or printed before it is brought in contact with the corrugated sheet, as has hitherto been done.

By means of the Wheels M and N and suitable gearings and connections the pastingroller F is given the same peripheral speed as that with which the fluted paper is drawn from the corrugating rollers, so that the rounded convex edges of the paper are simply pressed against the surface of the roller and not scraped across, so as to fill in the corrugations with paste where it can be of no use and will require extra time for drying, and the roller K is given like speed, so that both the fluted and plain sheets move at an even rate over the roller G. WVith two or more rollers in contact with the primary corrugating-roller a greater pressure and heating-surface is had and deep and permanent corrugations secured with a rapid motion of the rollers and the capacity of the machine largely increased. It is advantageous also to use large rollers in conjunction with small ones, as a series of small rollers alone do not afiord sufficient heating-surface, and when two or more large rollers are used together in forming a deep flute there is danger of breaking the paper in the process on account of the resistance offered by the great number of engaging-teeth to the free slipping of the excess of paper required to form the flutes, while after a small roller has been used to draw in the paper and give it the shape intended a large roller may be effectively em ployed to add proper finish and permanent set, the teeth of such a roller being of a form.

what Iclaim as new, and desire to secure by Letters Patent, is

1. In a machine for fluting paper, the combination of a primary fluted roller, a fluted roller of small diameter in rolling contact with said primary roller and adapted to draw in the paper and give it the shape intended, and a larger fluted roller also in rolling contact with said primary roller, arranged and operating substantially as and for the purpose set forth. I

2. In a machine for fluting paper, the combination of a fluted roller, a second fluted roller in rolling contact therewith, and a support acting upon the second roller between the journals and opposite to the first-named rollers, whereby the same is stiffened and the pressure increased, substantially as described.

3. In amachine for fluting paper, a primary fluted roller, in combination with two or more fluted rollers in rolling contact therewith and curved guiding-bands extending partly around said first-named roller and between it and one or more of the rollers inrolling contact therewith, grooves being formed in said last-named rollers to allow for said bands, substantially as described.

4. In a machine for manufacturing packing and lining fabrics, the combination of a pri.

mary fluted roller, two or more fluted rollers in rolling contact therewith, a pasting-roller adapted to move at the same peripheral speed as the fluted rollers, guiding-rollers adapted to bring the strip of paper fluted by said rollers in contact with said pasting-roller, and driving and guiding rollers adapted to bring a strip of backing-paper against said fluted strip, substantially as described.
